I use the TIM4 to get the hall sensors for a BLDC motor. In addition to that, I want to generate a PWM signal on the TIM4-CH4 to control a small brushed motor. The problem is that the period of the TIM4 is set to U16_MAX
Code:
// Set full 16-bit working range
TIM_HALLTimeBaseInitStructure.TIM_Period = U16_MAX;
TIM_HALLTimeBaseInitStructure.TIM_ClockDivision = TIM_CKD_DIV1;
TIM_TimeBaseInit(HALL_TIMER,&TIM_HALLTimeBaseInitStructure);
but I need at least a timer period set to 0x00FF to generate a valid PWM for the brushed motor.
My question: If I set
Code:
TIM_HALLTimeBaseInitStructure.TIM_Period = 0x00FF;
what other modifications is needed in the code for the hall sensors?
Thank you!
